i have oced my i5 to 4ghz but not changed the voltages they are all auto*cpu ring V*
and the *cpu V*
when im stressing it going almost up to 1.3 isnt that bad for the cpu ?
 
Solution
For 4 Ghz, I used OC genie on my board and it uses 1.127V max (using prime95) so you can use that as a starting point. it gets up to 61C using a coolermaster hyper 212 evo.

hi Yogi i have a question if my cpu runs at 1.3 and bellow how long will it last?
i have a h80i cooler
+ i tried change my cpu voltage to 1.100 it ran ok
but do i also have to change my cpu ring bus voltage?
 


It will last a very long time - prolly until the comp. becomes obsolete anf you need to replace it.

hi yogi :D i got into the bios and turned enchanced tubo on/enabled so it would go up to 3.8 as it says on the box when u are building your computer tried to run 2 stress programs but the Voltages was dramaticly diffrent take a look at this http://i.imgur.com/MysvM23.png its prime 95 and intel burn at MAX both

You must have your Vcore set to "Adaptive" voltage setting in the BIOS. Stress testing should always be done at a fixed voltage on Vcore by selecting "Override" Vcore in BIOS.

isnt there a easy 4ghz OC to the i5 4670k video or setting that i can set my voltage and cpu ratio to ?

1.150 to 1.200 v. should be good for about 4.0 to 4.2 GHz on "Most" unlocked Haswell CPUs.

u saw in the picture the voltage was diffrent from both but why would the computer try and hurt itself?

It is the result of the stress test placing an unusual load on the CPU.

and lets say that the cpu was on 1.3V all the time how long would last in years :D ?

I don't know and I don't really care because a fixed 1.300 v. is ONLY used during stress testing. For "normal" everyday purposes, "Adaptive" or variable voltage will do just fine, and with a "Balanced" setting in Windows Advanced Power Options will allow the CPU to slow down and operate at a reduced voltage when at low loads.
